I try to use Zeos with ado protocol to fill a small table with DBGrid. Database is MSAccess and have one autoincrement field. In dbgrid I leave that field empty and on post I receive a error message "try to assing a null vaalue to a variable that is not a Variant data type".
But when I try the same combination with Delphi ADO driver, everything works without problem and the autoincrement field get (automaticly) corect value.

Did I miss something? I use Zeos with MSSQL and MySQL and there are Sequencies that you could use for autoincrement, but there is no Seq in Access.
How to get autoincrement value in Zeos?
